Italian High Renaissance Painter and Inventor, 1452-1519 Italian High Renaissance Painter and Inventor, 1452-1519 Florentine Renaissance man, genius, artist in all media, architect, military engineer. Possibly the most brilliantly creative man in European history, he advertised himself, first of all, as a military engineer. In a famous letter dated about 1481 to Ludovico Sforza, of which a copy survives in the Codice Atlantico in Milan, Leonardo asks for employment in that capacity. He had plans for bridges, very light and strong, and plans for destroying those of the enemy. He knew how to cut off water to besieged fortifications, and how to construct bridges, mantlets, scaling ladders, and other instruments. He designed cannon, very convenient and easy of transport, designed to fire small stones, almost in the manner of hail??grape- or case-shot (see ammunition, artillery). He offered cannon of very beautiful and useful shapes, quite different from those in common use and, where it is not possible to employ cannon ?? catapults, mangonels and trabocchi and other engines of wonderful efficacy not in general use. And he said he made armoured cars, safe and unassailable, which will enter the serried ranks of the enemy with their artillery ?? and behind them the infantry will be able to follow quite unharmed, and without any opposition. He also offered to design ships which can resist the fire of all the heaviest cannon, and powder and smoke. The large number of surviving drawings and notes on military art show that Leonardo claims were not without foundation, although most date from after the Sforza letter. Most of the drawings, including giant crossbows (see bows), appear to be improvements on existing machines rather than new inventions. One exception is the drawing of a tank dating from 1485-8 now in the British Museum??a flattened cone, propelled from inside by crankshafts, firing guns. Another design in the British Museum, for a machine with scythes revolving in the horizontal plane, dismembering bodies as it goes, is gruesomely fanciful. Most of the other drawings are in the Codice Atlantico in Milan but some are in the Royal Libraries at Windsor and Turin, in Venice, or the Louvre and the École des Beaux Arts in Paris. Two ingenious machines for continuously firing arrows, machine-gun style, powered by a treadmill are shown in the Codice Atlantico. A number of other sketches of bridges, water pumps, and canals could be for military or civil purposes: dual use technology. Leonardo lived at a time when the first artillery fortifications were appearing and the Codice Atlantico contains sketches of ingenious fortifications combining bastions, round towers, and truncated cones. Models constructed from the drawings and photographed in Calvi works reveal forts which would have looked strikingly modern in the 19th century, and might even feature in science fiction films today. On 18 August 1502 Cesare Borgia appointed Leonardo as his Military Engineer General, although no known building by Leonardo exists. Leonardo was also fascinated by flight. Thirteen pages with drawings for man-powered aeroplanes survive and there is one design for a helicoidal helicopter. Leonardo later realized the inadequacy of the power a man could generate and turned his attention to aerofoils. Had his enormous abilities been concentrated on one thing, he might have invented the modern glider.   Related Paintings of LEONARDO da Vinci :. | Study fur the Sforza-Reiterstandbild | Annunciation (detail) sg77 | Study of the proportion of horses | St Jerome sgyu | Details of Mona Lisa |

Nash, Paul
English, 1889-1946 Painter, printmaker, designer, writer and photographer. Although he briefly attended the Slade School, London, in 1910, he was essentially self-taught. His first one-man show was held in 1912 at the Carfax Gallery, London, where he showed a set of shadowy landscapes and imaginative drawings that look back to the Pre-Raphaelites and late 19th-century illustration. Between 1910 and 1914 he paid little attention to Post-Impressionism and the modern movements in London.

Albert Baertsoen
Belgian, 1866-1922.Belgian painter and etcher. The son of a successful mill-owner and an excellent musician, he was a pupil and friend of Gustave Den Duyts (1850-97), and later, at the Ghent Acad?mie, of Jean Delvin (1853-1922). He was involved in the exhibiting society LEssor in Brussels as well as the triennial salons held in Brussels, Antwerp and Ghent in rotation. Among his earliest important works are The Scheldt at Dendermonde (1887; Ghent, Mus. S. Kst.), which he painted beside Isidore Meyers (1836-1917) and Franz Courtens in a Realist style characteristic of the Dendermonde school. In 1889-90 he attended the studio of Alfred Roll in Paris, where he met Jacques-Emile Blanche and Charles Cottet, and became particularly closely associated with Frits Thaulow, Emile-Ren? M?nard and Edmond Aman-Jean. He exhibited regularly at the Salon in Paris. Although Baertsoen is considered to be one of the first Belgian Impressionists, he belonged to no particular school. He was more than a descriptive landscape painter, for he sought to evoke through the depiction of the natural world a mood of melancholy and resignation. He painted silent streets, rocks, rivers and canals in Bruges, Li?ge, Nieuwpoort, Diksmuide and in London, where he stayed during World War I. His most important paintings, however, were inspired by his native town, Ghent, of which he built up a remarkable portrait over the years in such works as Barges in the Snow (1901) and Ghent in the Evening (1903; both Brussels, Mus. A. Mod.). A broad, spontaneous technique, great delicacy of nuance, deep sincerity as well as a certain meditative quality characterize his work, which is limited in quantity. Baertsoen played an important role in Belgian cultural life of his period and was elected to the Acad?mie Royale des Beaux-Arts in 1919.
